| 1. | Take the laser diode as the photoelectric detector ' s lamp - house , the optical system forms images of the sign , the double photoconductive resistance detects the excursion of the sign , a / d converter finishes a / d convert , the data is fuzzy processed by micro computer
光电探头采用激光二极管作为光源，光学系统完成标志的成像，双光敏电阻检测标志线的偏移， a / d转换器完成偏移信号的模数转换，数据由微机进行模糊处理。 |
